7 Application filed August 16, 1915. Serial No. 45,680.

To all whom it may concern:

Be. it ,known that I, 'HARoLn N. PALMER, United States, residing at New London, in the county of New London,

in the State ,of Connecticut, have invented a-certain new and useful Improvement in Apparatus for Closing Windows at Predetermined Times, of which the ,following is a specification, reference being had to the accompanying drawings.

4 The object of this invention is to provide 1 a reasonably cheap and simple mechanism,

controlled as to its action by clock mecha- -nism, whereby windows which are opened for 'ventilative purposes during the night maybe automatically closed at a predetermined hour in the early morning, thus rendering it unnecessary for a person sleeping inthe room to arise for the' special purpose of closing the window; in fact, rendering it unnecessary for the said sleeper to tax his mind with the matter of closing such windows. It is my intention further to so constructed.

' bythe annexed drawings,

detached, view of the said closing apparatus. Fig; 3. is a further enlarged view of the means by which the window i's'latched in its -(open).. position, and Fig. 4

is a viewjof a lever which is operated, by

I cially provided to W clock mechanism, to release the latching mechanism just referred .to. Fig. 5 is a detached, plan, View of a plate or bracket, by means of which the window-operating mechanism is connected tothe window sash. Fig. 6* is a: longitudinal, central, sectional view of plunger mechanism which is speprevent the too rapid closing of the window.

In these drawings the numeral 10 indicates a window frame and 11 denotes a sash slidably mounted in said frame. Secured to the top of the sash is a plate 12 which overhangs the inner face of the sash, and immediately below said plate is clo'ck mechanism of ordinary construction, including alarm mechanism, which is securedto the window sill 14. Secured to, and depending from, the plate 12 is a rod 15 whose lower. end bears a packed. piston 16 that is slidably mounted in a tube 17 which latter is secured to the window sill.' When the window is raised the piston head 16 is drawn upward 1n tube 17 and, when the said window is released, the plston plunger and the tube 17,

cohperate, with a restraining and cushioning'efl'ec't, to prevent the sash from coming down with a run. Instead, however, of the described piston plunger other restraining means could be utilized if desired as, for example, ordinarycords, and weights ofslightly less weight than the window.

Mounted to slide in a guide-ring 18, secured to the tube 17, is a rod 19 whose upper end is offset, as seen most clearly in Fig. 3,

said offset portion being connected with a bell-crank-lever 20 which'i's fulcrumed-to the tube 17 at 21; the other end of said bell: crank-lever being connected to a bolt or latch 22 which is adapted to slide in an tube 17 in a direction, as here opening in the angles to the longitudinal shown, at right "center of the rod-=15, and so as to engageand enter notches 23 in said rod 15 and thus retain the said rod and the attached sash in their raised positions until such time as it is desired tohave'the window closed. Inorder to thus release, and close, the window I connectthe lower end of rod 19 with one end of, a lever 24 (see Fig. 4); the other end I of'said lever being located in the path of any movable part of a clockalarm, and in such relation to said alarm that, when the latter goes ofiat a predetermined hour, the rod 19 will be slid downward a dis-v tance 'sufiicient to withdraw the end of bolt 22 from latching engagement with the notch of piston rod 15 and thus permit the sash to drop t3 be desire to assist the sash positively 'in its descent a steel tape 25 may connect the plate 12 with a revoluble drum 26 which latter may be operated by a barrel spring within the said drum.

constructed and it provides means for automatically closing such windows at predetermined times.

Having thus described my invention 1' its closed position. If it should described window-closing device may be readily applied to windows as ordinarily claim as new and wish to secure by Letthe other arm of said angular lever being ters Patentequipped to engage and retain the first re- 10 A window closing apparatus,v including ferred to rod member in elevated position, an inclosed rod member connected to the said additional rod member also being s'window sash, an additional rod member equipped with a fulcrumed lever at its lower having vertical movement, an angular lever, 'end, and means adapted to actuate said one arm of said lever being connected to the lever at a predetermined time.
